Product Details

We are proud to release the new CTS Turbo 3.5' Stainless Steel downpipe for the MK2 VW Tiguan/Audi Q3 (new) AWD 1.8T/2.0T High-Flow Cat.  Unfortunately, the factory downpipe that comes as standard equipment in your car was designed for anything but performance.  The factory downpipe severely restricts exhaust flow and therefore has adverse effects on horsepower, especially once your car is “chipped”.  The CTS Turbo High-Flow Cat will allow for your exhaust gases to flow smoothly, freeing up the additional ponies that you want, all while looking amazing.  Highlights of our downpipe include CNC machined turbine discharge (downpipe) flange, mandrel bent 3.5' to 3.0' stainless steel tubing, modular design making installation of a catalytic converter simple and straight forward, smooth transitions allowing for optimal exhaust gas flow.

Are you worried about emissions and inspections?  Don’t worry, our optional catalytic converter should satisfy prying eyes. Precision fabrication, unparalleled quality and great price point all make the CTS Turbo MK2 AWD Tiguan High-Flow Cat a must have for any VW enthusiast that values performance and their pocketbook.
